The invention discloses a construction method for unequal-height folding and splicing sequential unfolding of an ultrahigh double-arch structure, which comprises the following steps of: 1, splicing two arches (1) on the ground, and positioning the bottoms of the two arches at double-arch mounting positions; a pin shaft node (2) is arranged between the bottom of the arch door and the ground; 3, supporting rods (3) are arranged on the two sides of the upper portion of the arch door and connected with the ground through pin shaft nodes; 4, climbing jacks (4) are arranged at the bottoms of the supporting rods, and the climbing jacks are hinged to the two sides of the upper portion of the arched door; 5, the climbing jack climbs upwards along the supporting rod, the hinged joints on the two sides of the upper portion of the arch synchronously climb, the arch rotates upwards, the supporting rod rotates downwards, and the supporting rod, the ground and the arch form a triangular statically determinate system; 6, the
